Question

Find the distance between the points. (9,-3) (-1,8)

Answer 1

`\text{Solution:}\\\text{Let }(x_1,y_1)=(9,-3)\text{\ and\ }(x_2,y_2)=(-1,8).\\\text{Using the distance formula,}\\\text{Distance between the points = }√((y_2-y_1)^2+(x_2-x_1)^2)=√(11^2+(-10)^2)\\\text{\ \ \ \ \ \ \ \ \ \\ \ \ \ \ \ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }=√(221)\text{\ units}`
